At The Australian Soap Kitchen, we choose to only use natural, plant-based ingredients. For scented soaps we use natural, pure essential oils that are extracted from plants. Essential oils provide a lighter scent in bar soap. Their synthetic counterparts (fragrance oils) on the other hand, provide a stronger scent and are commonly used in the beauty/body product industry. These fragrance oils can be made up of many synthetic chemicals with questionable effects on skin and general health and therefore we choose to absolutely not include these in our soaps.
